m: nanni: nun mu "uni-mm. mumnawn n c t the improved features of construction, in-

the web thereof. That is, it is preferable to havethebar web disposed at a somewhat greater distance from the web ofthe rail than is customary, because of the known fact that such a locatlon of the weboftlie bar contributes to the efliciency of the foot of the bar, while atthe same time permitting of a very substantial enlargement, both laterally and vertically of the head o'fflthe' bar, so that the latter may be, greatly uncreased in strength.

best or: preferred form, the present invention involves a splice bar including a Web member A, a head member B, andfafoot memberfC,

with the web member Ahaving, a position wherein it occupies an advanced outward location from the web of the rail R, and the main body of metal therein is-Iintersec'ted by a vertical rail, head, Z e present invention, accordingly, preferably utilizes the distinct advam tagev of an-a'dvanced outward location of the Web of the bar, andprovides for the strengthening of the upper chord head, and the web member, by means of the feature of increasin thelbod or thickness of I met,al,-ab'ove the or'izonta' neutral axis, by

graduated increments or enlargements at the resist the loading stresses.

The distlnctlve and novel feature referred to, namely, that of the graduated increments.

or enlargements of metal above the zontal neutral axis, is clearly Shown in the drawings. Referring thereto it will first be observed that the horizontal; neutral axis in the illustration occurs substantially at the line designated N. A., below the line of the joint bolts 1', and atthis place the minimum amount of metal may be used, thereby forin 7 ing a substantially narrow neck portion .or

area 2 connecting the web member A with the foot member C of theibar. v 4

Above the reducedneck portion 2, thevweb member A ,of the bar is of a graduated formation .upon the inner side thereof. As

, shown, the said web member is providedat its outer side with a flat vertical bolting face 3 against which is seated the nut bearing member or washer 4;, against whichbears the looking nut 5; while the inner side of :Hthefnpright web member is of the stepped v formation referred to. This stepped forma -s tion involves the entire inner side of the bar from the reduced neck portion up to the inside head projection 6,, and, primarily cons sts of .a graduated stepping up in the thiclme'ssof the metal from the zone or area 0i. minimum thickness to vthe zone or area of maximum thickIlQSSih the" head of the lane at the outer side of'the bar; This graduated stepped formation,

progressively increased web enlargements D -andE respectively. The first of these enlargements (D) contains less area of metal than 'the next succeeding enlargeshoulder 80f the upper web enlargement E occurs in a plane" between the top and bottom of the bolt holes. Thus, the said enp i largement-E extendsattheinner side of the Therefore, it is to be observed'that, in its bar, from its ribo'r' shoulder 8, between the top and bottom of the bolt holes, to the inchningshoulder 9. at the under side of the inner head projection 6, andlthe latter is provided with an inner substantially vertical clearance face" 10 which is spaced from the rail web to permit of the'necessary ad j' lls'tmcnt of the bar'at thisIpointJ 'In connection with-this step formation of the inner side ofthe bar, it will be observed that the straight surfaces. between the stepping ribs 7 and Bare maintained substantially parallel withthe vertical outer face of the bar, thereby preserving a parallelism between the outer and inner sides of'the bar which is very desirable to facilitate a cold punching 7 I hereinafter more fully referred to. places where reinforcement is most'neededtooperation, as well s accurate punching, as V In addition. to the inside steppedlformathan of the bar,;as"described, the head of the bar is materially reinforced or strengthened by the outside plural rib formation thereof. This plural rib formation essentially consists in the head member B having an outer projection 11 extending up to the line of wheel flange clearance l2 and provided with stepped projections-ofmetal 13 and 14, respectively These stepped projections of metal are in the form of outwardly project ings ribs which materially increase the area of metallinthe head member by thewviden ingand deepening; thereof at, the outer side of the loar Ani it will be observed, that, by reason of employing a nut bearing memher or washer 4 which is truncated or cut aWaya-t one side at at 1-5, the metal'in the lower or innermost projection of rib 14 may be. carried: substantially into .a horizontal 'planeat the top of the; bolt hole. This 7 brings the metal so low at this point as to materially deepen the'outerhead projection 11 and provide for a very substantial reinforcement of the head of the bar. The location and disposition of the metal in the lowermost rib 14 are such that the metal is carried well below the top line of the nuts I (the long diame er being the measure) which has been foundto be a very importantand practical feature inthe constructionof splice bars of the reinforced-head type.

That is to say, the step formation at the inner side of the bar is of practical importance, not only to provide for the graduated reinforcement from the horizontal neutral axis upward to the head of the bar, but also provides, at

the inner side of the bar, upright or vertical faces substantially parallel to the adjacent portion of the railweb, thus making it possible fora reinforced bar of this type to have the boltholes punched therein with the same facility as the punching of the bolt holes in The operation of punching the bolt holes is rendered more difiicult and less accurate where the punch is required to pass throu h a surface not at substantially right ang es thereto, or in other words, through an inclining or curved surface, such as shown in some of the references of record. Accordingly, the step formation at the inner side of the joint bar represents an improvement in the art of practical importance, both from a manufacturing standpoint and from the standpoint of providing a desirable means of properly balancing the metal distributed throughout the bar above the horizontalneutral axis. In this connwtiomit will be observed that the construction referred to per- 7 mits the web of the bar, at its maximum thickness, to be substantially of a thickness equal to the diameter of the bolt holes within the bolt hole punching zone, thereby permitting the bars to be punched cold 5 at the same time permitting of the thinning out of the metal toward the horizontal neutral axis to obtain the graduated reinforcement desired.

From the fore oing it is thought that the construction an many advantages of the herein described improvements will be I readily understood without further descrip- 'tion, and it is to be'noted' that changes in the'form, proportion and minor details of the construction, as fall within the scope of the appended claims, may be to trauma wither;
